Thanks Nicolai.... I have increased the NUMBER_DATA_BUFFERS_DISK and NUMBER_DATA_BUFFERS TO 128 for starters.... I have moved the backups to a isolated nic from the public traffic on the client. I still see minimal increase in ping times on the backup nic and also from time to time i may miss a packet. However, the network continues to function from the public and backup nic. So in conclusion, the fix was to lower the SIZE_DATA_BUFFERS_DISK to minimum 262144. I will mark this one resolved after a week of doing backups to ensure nothing else creeps up. As a side note i did increase tcp sliding window on the client solaris but i dont believe there was any affect on increasing the window.
Thanks
